I seriously dont remember anyone who can sense/read chakra that well. And the only reason the byakugan dude could tell is because he fought the guy whose body parts Danzo stole/took/borrowed. No one(in konoha) said that they didnt know he had it. And if no one really knew then the only people who could tell were the hyugaas and it might be....weird to explain why you were looking through a seemingly decrepit old mans clothes
